formal evening dress: vest or no?

[JSFMACLJR]

Because, let's face it, the really traditional way to wear tartan includes wearing two or three or four at once and quite possibly without any notion of clan significance. That is assuming you go for such newfangled innovations as loomed cloth, instead of good old traditional fur.

Having said all of that and raised a few hackles, I WILL say that I believe a tartan cummerbund with a tartan kilt is probably asking for trouble.

Shouldn't that be "the really HISTORICAL way to wear tartan"?
